Game try

Last updated

A game try (also called a game trial bid) in the card game of bridge is a bid that shows interest in bidding a game and asks partner to help in making the decision.

A card game is any game using playing cards as the primary device with which the game is played, be they traditional or game-specific.

Contract bridge card game

Contract bridge, or simply bridge, is a trick-taking card game using a standard 52-card deck. In its basic format, it is played by four players in two competing partnerships, with partners sitting opposite each other around a table. Millions of people play bridge worldwide in clubs, tournaments, online and with friends at home, making it one of the world's most popular card games, particularly among seniors. The World Bridge Federation (WBF) is the governing body for international competitive bridge, with numerous other bodies governing bridge at the regional level.

For example, (using Acol or Standard American bidding) if opener, with around 16-17 HCP, bids 1 and partner responds 2 (showing 6 – 9 support points) opener is in a quandary: if responder has a maximum strength hand, with well-positioned high cards, then game will probably make; but the information revealed so far is not accurate enough for either partner to decide whether to play in game or only part score.

Acol is the bridge bidding system that, according to The Official Encyclopedia of Bridge, is "standard in British tournament play and widely used in other parts of the world". It is a natural system using four-card majors and, most commonly, a weak no trump.

Standard American is a bidding system for the game of bridge widely used in North America and elsewhere. Owing to the popularization of the game by Charles Goren in the 1950s and 1960s, its earliest versions were sometimes referred to simply as 'Goren'. With the addition and evolution of various treatments and conventions, it is now more generally referred to as Modern Standard American. It is a natural bidding system based on five-card majors and a strong notrump; players may add conventions and refine the meanings of bids through partnership agreements summarized in their convention card. One standardised version, SAYC, is widely used by casual partnerships and in online bridge.

In contract bridge, various bidding systems have been devised to enable partners to describe their hands to each other so that they may reach the optimum contract. Key to this process is that players evaluate and re-evaluate the trick-taking potential of their hands as the auction proceeds and additional information about partner's hand and the opponent's hands becomes available.

Originally, opener would make a game try by bidding 3 (inviting game) and responder would then bid game with maximum (8-9) points or pass with minimum (6-7) points. Modern game try bids permit more accurate decision-making. Following a simple raise by partner (e.g. 1 – 2), opener bids a new suit either to show extra values or to ask responder to show more about his values. There are a variety of methods to do so including long suit, short suit, or help suit game tries and partnership agreement is required. [1]

Whichever method is adopted, responder and opener will collaborate to evaluate the additional information and make one of the following choices: sign off in three of the agreed major; jump to game in the agreed major; jump to game in notrump if the suit is a minor; or make a counter try in yet another new suit. When opener has a very strong hand, slam investigation may also be undertaken.

With a major suit fit

Prior partnership agreement is needed to determine which variety of game try is being used:

With a minor suit fit

Because 11 tricks are required for a minor suit game, most players prefer to investigate the possible optimum contract of 3NT before settling for a minor suit contract (game or part score) and thus a trial bid new suit shows a stopper in that suit for NT purposes, e.g.: 1 – 2; 2 shows game going strength and a stopper in spades

If opener has a weak hand

When using any of the above methods of game tries, it is common that a rebid of three of the agreed suit is not a game try, but a preemptive strategy intended to inhibit the opponents from entering the auction. Responder must pass, as in this example: 1 – 2; 3 – Pass.

Preempt is a bid in contract bridge whose primary objectives are (1) to thwart opponents' ability to bid to their best contract, with some safety, and (2) to fully describe one's hand to one's partner in a single bid. A preemptive bid is usually made by jumping, i.e. skipping one or more bidding levels. Since it deprives the opponents of the bidding space, it is expected that they will either find a wrong contract of their own, or fail to find any. A preemptive bid often has the aim of a sacrifice, where a partnership bids a contract knowing it cannot be made, but assumes that, the penalty will still be smaller than the value of opponents' bid and made contract.

If opener has a very strong hand

If opener has such a good hand that a slam seems possible even following a single raise by partner, then more information about responder's hand can be obtained by using a game try bid. If responder rejects the game try, opener can sign off in game. If responder accepts the game try, then opener can further investigate the slam.

Stayman is a bidding convention in the card game contract bridge. It is used by a partnership to find a 4-4 or 5-3 trump fit in a major suit after making a one notrump (1NT) opening bid and it has been adapted for use after a 2NT opening, a 1NT overcall, and many other natural notrump bids.

The Jacoby transfer, or simply transfers, in the card game contract bridge, is a convention in Standard American bidding systems initiated by responder following partner's notrump opening bid that forces opener to rebid in the suit ranked just above that bid by responder. For example, a response in diamonds forces a rebid in hearts and a response in hearts forces a rebid in spades. Transfers are used to show a weak hand with a long major suit, and to ensure that opener declare the hand if the final contract is in the suit transferred to, preventing the opponents from seeing the cards of the stronger hand.

Zar Points (ZP) is a statistically derived method for evaluating contract bridge hands developed by Zar Petkov. The statistical research Petkov conducted in the areas of hand evaluation and bidding is useful to bridge players, regardless of their bidding or hand evaluation system. The research showed that the Milton Work point count method, even when adjusted for distribution, is not sufficiently accurate in evaluating all hands. As a result, players often make incorrect or sub-optimal bids. Zar Points are designed to take many additional factors into consideration by assigning points to each factor based on statistical weight. While most of these factors are already implicitly taken into account by experienced players, Zar Points provides a quantitative method that allows them to be incorporated into bidding.

The weak two bid is a common treatment used in the game of contract bridge, where an opening bid of two diamonds, hearts or spades signifies a weak hand with a long suit. It is used in combination with the strong two clubs bid and is a form of preemptive bid. The term refers to an opening bid, and is not to be confused with the "weak jump overcall", which denotes a similar type of hand, but is bid over an opponent's opening bid.

Jacoby 2NT is a bridge convention in which a bid of 2NT over partner's opening bid of one heart or one spade shows a hand with both

Bridge bidding systems that incorporate a strong 2 clubs opening bid include modern Standard American, standard Acol, 2/1 game forcing and many others.

Muiderberg is a bidding convention in the card game bridge. It is a two-level preemptive opening based on a two-suiter with precisely a five-card major and a minor suit. In Muiderberg the 2 opening denotes five hearts and an unknown minor suit, whilst 2 denotes five spades and an unknown minor suit. The convention is also known as the Dutch Two, Lucas Two or Woo Two opening. The convention is named after the Dutch village Muiderberg, the residence of the designers of the convention - Onno Janssens and Willem Boegem.

In contract bridge, a cue bid is either a bid of the opponents' suit, or "slam seeking": a slam-investigating bid made during an auction's later rounds that shows control of a suit.

In natural bidding systems most notrump (NT) bids are made with balanced hands and within a narrowly defined high card point (HCP) range. In these systems, such as Acol and Standard American, NT bids are limit bids and therefore are not forcing. Bearing in mind the need to bid only to the optimum contract and no higher, bids above game are made only in specific circumstances, one of which is to alert partner to the fact that a slam may be possible and inviting partner to take part in the decision making process.

A reverse, in the card game contract bridge, is a bidding sequence designed to show additional strength without the need to make a jump bid; specifically two suits are bid in the reverse order to that expected by the basic bidding system. Precise methods and definitions vary with country, bidding system and partnership agreements.

EHAA is a highly natural bidding system in contract bridge characterized by four-card majors, sound opening bids, undisciplined weak two-bids in all four suits and a mini notrump, usually of 10–12 high card points.

The Useful Space Principle, or USP, was first articulated in a series of six articles in The Bridge World, from November 1980 through April 1981. The USP is expressed succinctly in The Bridge World glossary as: "a partnership's assigning meanings to actions so that the remaining bidding space matches the needs of the auction."

New Minor Forcing (NMF), is a contract bridge bidding convention used to find a 5-3 or 4-4 major suit fit after a specific sequence of bids in which opener has rebid one notrump. The convention is triggered by responder at his second turn by an artificial bid of two in an unbid minor; it requires that he hold five cards in the major he has previously bid and an unlimited hand ranging in value from at least game invitational strength to that sufficient to have interest in slam; he may also hold four cards in the other major. Accordingly, there are six bidding sequences in which the New Minor Forcing bid may be applied:

The Baron bidding system in contract bridge was developed in England in the 1940s as a variant of Acol and incorporates several conventions including the Baron Three Clubs, the Baron Notrump Overcall, the Baron Two Notrump Response and the Baron Two Spades and Three Spades.

Bridge base basic, also known as BBO basic, is a bidding system for the game of bridge based on Standard American Yellow Card. It is simplified, suitable for beginners, and widely used in internet bridge particularly on Bridge Base Online. It is taught in Fred Gitelman's educational software called Learn to Play Bridge that is available as a free download from the American Contract Bridge League's website.

Transfer Walsh is a bidding convention used in contract bridge. After a 1 opening bid, responses of 1 and 1 show heart and spade suits respectively. The "Walsh" terminology refers to the fact that these bids may conceal an equal or longer diamond suit. It allows opener to play a greater proportion of major-suit and no-trump contracts, particularly when using five-card majors.
